Reflexes, or reflex actions, are involuntary, almost instantaneous movements in response to a specific stimulus. Reflex arcs that contain only two neurons, a sensory and a motor neuron, are considered monosynaptic. Examples of monosynaptic reflex arcs in humans include the patellar reflex and the Achilles reflex.
A microwave oven uses microwaves. This is a kind of electromagnetic wave. The energy source for the microwave oven is AC (alternating current, electricity), available in many houses.
every microwave oven contains a magnetron a tube in which electrons are affected by magnetic and electric fields in such a way as to produce micro wavelength radiation at about 2450 mega hertz mhz or 2 45 giga hertz ghz
